• The latest generation of Honda's solar cars, the Dream, broke the record in this year's World Solar Challenge (WSC). Starting in Darwin on Sunday, 26th October, the two-man, four-wheel vehicle completed the 3010-kin-course to Adelaide in just 33 hours and 32 minutes, taking two and a half hours off the remarkable time set three years ago by the previous Honda Dream team in a lighter, one-man, three-wheel vehicle.

  The latest Dream managed an average speed of 89.76 km/h, compared to 84.96 km/h for the previous one, despite stormy winds and uphill slope slowing all the competitors during the event's second day. However, during the final day's run from the South Australian desert mining town of Coober Pedy to Adelaide, the Dream cruised(以发动机效率最高的速度行驶) at 100 km/h, occasionally accelerating to 110 km/h. "We are very tired and very happy," the Dream team's project leader, Masashi Kitagawa, told the crowd of reporters waiting at the finish line at Adelaid's Technology Park. The School of Biel team placed second, an hour and 28 minutes behind the Dream, having averaged 86 km/h. The Swiss engineering school is Honda's perennial rival(竞争对手) in this event, having beaten Honda in 1990 to set a course record of 38.50 hours. However, they placed a distant second to the Honda Dream in the 1993 event. A full report, along with pictures, will appear in the next issue of Honda: The Magazine. The phrase "the latest generation of Honda's solar ears, the Dream" implies that ______. A．Honda is a car maker B．the Dream is a model of solar car produced by Honda C．Honda's solar technologies are being improved over time D．all of the above

• To get a sense of how women have progressed in science, take a quick tour of the physics department at the University of California, Berkeley. This is a storied place, the 36 of some of the most important discoveries in modern science—starting with Ernest Lawrence’s invention of the cyclotron (回旋加速器) in 1931. A generation ago, female faces were 37 and, even today, visitors walking through the first floor of LeConte Hall will see a full corridor of exhibits 38 the many distinguished physicists who made history here, 39 all of them white males.

  But climb up to the third floor and you’ll see a 40 display. There, among the photos of current faculty members and students, are portraits of the 41 head of the department, Marjorie Shapiro, and four other women whose research 42 everything from the mechanics of the universe to the smallest particles of matter. A sixth woman was hired just two weeks ago. Although they’re still only about 10 percent of the physics faculty, women are clearly a presence here. And the real 43 may be in the smaller photos to the right: graduate and undergraduate students, about 20 percent of them female. Every year Berkeley sends its fresh female physics PhDs to the country’s top universities. That makes Shapiro optimistic, but also 44 . “I believe things are getting better,” she says, “but they’re not getting better as 45 as I would like.” A) circumstance B) confidence C) covers D) current E) deals F) different G) exposing H) fast I) honoring J) hope K) presently L) rare M) realistic N) site O) virtually
